    According to Agricultural Research Service (ARS) entomologist and research leader Tracy Leskey, laboratory trials show that brown marmorated stink bugs are attracted to blue lights—lights that attract fewer non-target insect species. She also tested a combination of visually attractive blue lights with chemically attractive pheromones. These studies about the effectiveness of both light and pheromone-baited traps will help researchers develop more effective stink bug traps in the future.

    This initiative includes more than 50 researchers from 10 institutions across the U.S. working together on this project team. The team of researchers has mobilized to form a defense against the invasive pest brown marmorated stink bug (BMSB). The project team is working to find management solutions for growers, seeking strategies that will protect our food, our environment, and our farms.
Native To:
Date of U.S. Introduction:
First confirmed in 2001 in Allentown, Pennsylvania, but specimens were collected as early as 1996 (Khrimian et al. 2008)
Means of Introduction:
Possibly arrived in shipping material (Gariepy et al. 2014)
Feeds on a variety of plants, including fruit trees, ornamentals, and some crops (Gariepy et al. 2014)
